由于Express版本限制为10 GB(无法弄清楚它是'每个数据库'还是作为一个整体,因为文档令人困惑,至少对我而言),我想知道有没有办法检查这个空间可用性,到目前为止我用了多少?我使用了互联网上的一些建议,但不知道我的所有数据库都显示出来了。

10 GB用于数据文件大小。您可以像这样获得每个文件的使用百分比:
;WITH x AS
(
SELECT name, [file] = physical_name, size = size * 8,
su_bytes = FILEPROPERTY(name, 'SpaceUsed') * 8
FROM sys.database_files
)
SELECT name, [file], size, SpaceUsed = su_bytes,
[SpaceUsed%] = CONVERT(DECIMAL(5,2), su_bytes*100.0/size)
FROM x;
如manual on sys.database_files
所示,size
列保持以8K页表示的大小,因此将该值乘以8会得到以千字节为单位的大小。同样适用于FILEPROPERTY(..., 'SpaceUsed')
的结果。要获得其他单位的金额,请相应地更改计算。

你是对的......做了一些谷歌搜索并找到了更好的解决方案:
SELECT name AS 'File Name' , physical_name AS 'Physical Name', size/128 AS 'Total Size in MB',
size/128.0 - CAST(FILEPROPERTY(name, 'SpaceUsed') AS int)/128.0 AS 'Available Space In MB', *
FROM sys.database_files;
更好:
SELECT DB_NAME(A.DATABASE_ID) AS DBNAME,A.NAME AS FILENAME ,
SIZE/128.0 AS CURRENTSIZE_MB,
B.RECOVERY_MODEL_DESC,A.TYPE_DESC ,
CASE WHEN IS_PERCENT_GROWTH = 0
THEN LTRIM(STR(A.GROWTH * 8.0 / 1024,10,1)) + ' MB, '
ELSE 'BY ' + CAST(A.GROWTH AS VARCHAR) + ' PERCENT, 'END +
CASE WHEN MAX_SIZE = -1 THEN 'UNRESTRICTED GROWTH'
ELSE 'RESTRICTED GROWTH TO ' +LTRIM(STR(MAX_SIZE * 8.0 / 1024,10,1)) + ' MB'
END AS AUTOGROW,A.PHYSICAL_NAME
FROM SYS.MASTER_FILES A JOIN SYS.DATABASES B
ON A.DATABASE_ID =B.DATABASE_ID
--WHERE A.PHYSICAL_NAME LIKE 'E%'
-- AND A.FILE_ID =2
ORDER BY A.SIZE/128.0 DESC
